DUET. DUET is a duet of two DNNs that combines the strengths of representation- and interaction-based models [1]}. DUET calculates the relevance between a query and a document using local and distributed representations and for this reason, has been classified as a hybrid model [2]}. By local representation we mean properties like the exact match position and proximity while distributed properties are synonyms, related terms and well-formedness of content.
